WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 48,088, dated November 18, 1890.

Application filed May 8, 1890. Serial No. 351,033. (No model.)

To aZZ whom, it may concern:

Be it known thatI, THEODORE SMITH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Window- Screens and Apparatus for Use Therewith, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, in which Figure 1 is an inside view in elevation of a window-case, showing my improved devices in position when in use. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a detail view of the bifurcated arrowhead catches and stops for engaging therewith. Fig. A is a perspective of the same, showing thumb-pieces for disengaging the catches.

The object of my invention is to provide a screen and receptacle for the same, by the use of which the screen may be used when desired without any trouble 011 the part of the operator.

Another object of my invention is to provide a screen which may be readily and easily secured and attached from the window-sash by one not particularly skilled in mechanics in the shortest possible time and with the least expense of physical and mechanical force.

Another object of my invention is to pro vide a screen which shall be neat in appearance and which shall snugly fit the windowframe and present the most artistic appearance possible for a device of this kind, so far as regards the means of attachment of the screen.

It is well understood that the screens ordinarily in use are too cumbersome and the plan of their operation such that much trouble is experienced in adjusting them to fit the spaces left by the open window.

In the accompanying drawings, A designates an ordinary window-sash provided with slot 17, provided with suitable escutcheon c.

B designates the screen and screen-frame, which is provided with suitable projections or staples f, adapted to fit into the openings in the bottom of the sash, and they are designed to be firmly held in place by suitable catches f f provided with posts H adapted to slide in slots J J in the window-sash.

A receptacle or casing is designated. by the letter O, and this casing or receptacle or well is let into the bottom of the window-sill and is of such dimensions as to facilitate the ready and easy insertion of the screen therein and also its ready removal therefrom when desired for use.

From the foregoing it will appear that the screen may be readily attached or detached; It may be stored away in the receptacle beneath the sill when not in use, and it may be readily attached to the window-sash and moved to the space left by the opening of the window when the use of the screen is necessary or desirable.

In some instances I make use ofspringcatches on the screen and have them engaged with plates in the bottom of the recesses in the window-sash similar to a bifurcated arrow-head engaging with the plate or stop f f", forming a spring-catch, as shown in Fig. 3.

Two floating hard-rubber rollers H H are used on either side of the screen in order to make the same work evenly and to assist in holding the screen in position when up; 0ther- Wise the extra weight would more than balance the sash-weights and cause the screen to fall. At the lower edges of the sills of the screen-frame I also provide two pivotal rollers H H, which serve to secure more perfect operation, while the rollers H H roll in recesses M M in the sides of the screen. The bifurcated arrow-head catches shown in Figs. 3 and 4 engage with stops f f*, which in this instance may be simply pins for that purpose. Thc resiliency of the springy metal will cause them to lock automatically as the screen and window-sash are brought together. They may be disengaged by thumb-pieces g g, by means of which they may be pressed together away from the stops.

What I believe to be new, and whatI therefore wish to secure by Letters Patent, is

1. In awindow-screen and well for the same, the combination of the window-sash, having perforations and slots and a catch, with a sliding screen having projections which register with the perforations in the sash and which are adapted to be locked into position catches for engagement with said springby the catches in the slots in the openings in catches, substantially as described. xo the'windowsash and the rollers at the sides In testimony whereof Iaffix my signature in of the screen, substantially as described. the presence of two witnesses.
